摘要:
Provided is an oxide superconducting wire material, wherein pinning of magnetic flux, under an environment in which magnetic field is applied, can be conducted efficiently towards any magnetic-field applying angle direction, to secure a high superconductive property. The oxide superconducting wire material (100) is provided with a metal substrate (110), an intermediate layer (120) formed upon the metal substrate (110), and a REBaCuO-system superconductive layer (140) formed upon the intermediate layer (120). RE comprises one or more elements selected from Y, Nd, Sm, Eu, Gd, and Ho. Oxide particles including Zr are distributed within the superconductive layer (140) as magnetic-flux pinning points (145), and the mole ratio (y) of Ba included within the superconductive layer (140) is, when the mole ratio of Zr is assumed to be x, within a range of (1.2+ax)≦y≦(1.8+ax), wherein 0.5≦a≦2.
